Question About Relocating Journal on Other Device
Hi. I'm using e2fsprogs 1.23 on a Roswell system with a patched 2.4.7
kernel (using patch ext3-2.4-0.9.5-247) and am trying to create an ext3
filesystem whose journal is located on another device. The incantation I'm
trying is:
mke2fs -j -J device=/dev/hdc2 /dev/hdc3

centos4.2:raid1:grub
Hi!
Whew, I have googled around a lot w/this but can't quite seem to come up
w/the right answer.
This system works beautifully w/nothing wrong w/it. But my goal is to be
able to test the raid system by just unplugging hda to mimic a faulty
drive and have it just carry on and boot from hdc.
md0 = hda1/hdc1 /boot (primary boot partitions on both drives)
md1 = hda2/hdc2 /

can't mount an LVM volume inCentos 5.10
I have a degraded raid array (originally raid-10, now only two drives)
that contains an LVM volume. I can see in the appended text that the
Xen domains are there but I don't see how to mount them. No doubt this
is just ignorance on my part but I wonder if anyone would care to
direct me? I want to be able to retrieve dom-0 and one of the dom-Us

LiveCD System recovery - Mounting LVM?
Hi,
I am trying to recover data from my old system which had LVM. The disk had
two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had
taken a backup of both partitions using dd.
Now I am booting of CentOS live cd for system restore. I recreated
partitions like previous system using fdisk and then used dd to dump all the
data onto it. I would like to mount sda2 as LVM, but I

what''s correct way of shrinking LVM based domU?
Hi all
I want to shrink one of my LVM based domU''s, but don''t quite know how to
do it.
I have searched the Wiki & HOWTO''s, and they all show you how expand /
enlarge a LVM based domU, but not shrinking it.
So, I stopped (destroyed) the domU, and then resized it as follows:
lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started

is it possible to resive a PV in LVM and add more LV's ?
Hi all
I have a remote server (i.e SSH access only) which was incorrectly
partitioned and I urgently need to get it up and running. It's got a 500GB
HDD, but the PV is only 10GB big, so I can't add more LV's to to. P.S. This
is on LVM, btw.
